Bone formation/Ossiffication Flashcards
1
Q
in which 4 situations does ossification take place
A
embryonic developement
bone growth during childhood
fracture repair
bone remodelling
2
Q
when does ossification start and end
A
begins before birth and ends at around 21 years old
3
Q
endochronal ossification
A
long bones beginning as cartilage models
ossification of long bones begin in the ossificationn centres of cartilage models
secondary centres develop to form the epiphysis
4
Q
how does growth in childhood begin
A
by production of bone in the epiphysal state
5
Q
which minerals are required for ossification
A
vitamins A, C and D, adequate calcium and phosphate is also required
6
Q
which hormones are responsible for ossification
A
tetsosterone
thyroxine
parathyroid
growth hormone
